bazel coverage not working for 0.0.9

[Ryang20718]

Description of the problem / feature request:

Bazel Coverage failing with rules_cc 0.0.9

Feature requests: what underlying problem are you trying to solve with this feature?

We're trying to uprev our rules_cc from ancient 0.0.1 to latest version as we prepare to migrate to bazel 7.0.0

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

test.cpp

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

BUILD

cc_library(
    name = "test_lib",
    srcs = ["test.cpp"],
)
cc_test(
    name = "test",
    srcs = [":test_lib"],
)

What operating system are you running Bazel on?

ubuntu 20.04

What's the output of bazel info release?

release 6.3.2

What version of rules_cc do you use? Can you paste the workspace rule used to fetch rules_cc? What other relevant dependencies does your project have?

0.0.9

What Bazel options do you use to trigger the issue? What C++ toolchain do you use?

I ran this with bazel 6.3.2 in the rules cc example section by adding the following section above. I'm using the cc toolchain configured by rules_cc.

System gcc is 9.0.0

Have you found anything relevant by searching the web?

@c-mita for triage
possibly similar to bazelbuild/bazel#20993

I can't even build the example in this repo with Bazel 6.0.0 or later...

Regardless, I suspect the issue is here:

rules_cc/cc/private/toolchain/unix_cc_toolchain_config.bzl

Line 997 in 35fe45e

name = "coverage",

The "coverage" feature is a duplicate of the "gcc_coverage_map_format" one, but the latter "requires" the former and there's a conflict since they provide the same "profile" symbol.

I got that issue too on Debian 12 with GCC 12. If you enable rool_cc toolchain coverage fails (because symbol profile is provided by several features. Using the built-in toolchains the issue is gone. To reproduce using the OP's code and BUILD file, use the following WORKSPACE.bazel.

workspace(name = "cov_issue")

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

# ----------------- rules_cc -----------------------------------
http_archive(
    name = "rules_cc",
    urls = ["https://github.com/bazelbuild/rules_cc/releases/download/0.0.10-rc1/rules_cc-0.0.10-rc1.tar.gz"],
    sha256 = "d75a040c32954da0d308d3f2ea2ba735490f49b3a7aa3e4b40259ca4b814f825",
)

load("@rules_cc//cc:repositories.bzl", "rules_cc_dependencies", "rules_cc_toolchains")
# ----------------------------------------------------

rules_cc_dependencies()
rules_cc_toolchains()

Running bazel coverage --noenable_bzlmod --combined_report=lcov //:test produces the error. Commenting the last two lines in the workspace file and running the bazel command again, succeeds.
